During 1995-1996 Rothamsted suction trap catches of aphids have been carried out in Latvia. Two suction traps are located in Cesis and Saldus - territorially two opposite sites of Latvia. It is the first time when suction traps are used in Latvia. The obtained data have been compared with similar catches in Sweden as well as with yellow water trap catches at Jelgava (Latvia). The dynamics of relatively important aphid species as vectors of plant viruses have been investigated. The investigation results show the most harmful species to cereals and potatoes.
